Specification of Letters Patent.

Patented Aug. 15, 1905.

Application filed August 10, 1904. Serial No. 220,287.

To all whom zit may concern:

Be it known that l, ALONZO H. FENCE, a citi- Zen of the United States,residing at Seinerville, in the county of Morgan and State of Alabama,have invented a new and useful Cultivatingmplement, of which thefollowing is a specification.

This invention relates to cultivating implements; and ithas for itsobject to simplify and improve the construction and operation ot thisclass of devices.

With these and other ends in View, which will readily appear as thenature of the invention is better understood, the same consists intheimprcvedconstruction and novel arrangement and combination of parts,which will be hereinter fully described, and particularly pointed out inthe claim.

in the accompanying drawings has been illustrated a simple and preferredform oi' the invention, it being understood that no limitation isnecessarily made to the precise structural details therein exhibited,but that such changes and alterations as i'all properly within the scopeof the invention may be resorted to when desired.

in said drawings, Figure 1 is a plan view of the implement complete.Fig. 2 is a side view. E ig. 3 is a sectional detail View oi' theadjusting-frame coupling.

Corresponding parts in the several figures are indicated throughout b vsimilar characters of reference.

The improved device comprises a draftbeam 10,to which draft-animals maybe hitched in the usual manner, said beam being provided with handles1l. The draft-beam is provided with depending hook-bolts 12 13, thepoints of which engage recesses, as 1A, in the under side oi" the beam,the latter being provided with perforations, as 12, for the passage ofthe shanks ofthe hook-bolts. The latter serve to securein position anannular trame 1A, consisting oi a ring ot' suitable dimensions,preferably made of iron wire or rod, circular in cross-section and ofsuitable dimensions, the ends oi' such wire or rod being' weldedtogether, so as to form an integral ring or frame oiI such diameter asto engage the hooked ends of the bolts l2 13, which are provided withtightening-nuts 2l 22, which may be tightened against the upper side ofthe beam, so as to secure the ring or frame .1A in contact with theunder side of the latter.

15 and 16 are clips straddling the ring 1A at approximately diametrically opposite sides of the latter and extending through a cultivator heador beam 17, which is formed with spaced horizontal sides which aresuiiiciently separated for the passage between said sides of eyebolts18, theheads oi' which 19' are partially extended between the spacedsides oi' the beam 17, as clearly seen in Fig. 1 of the drawings, so asto prevent said eyebolts from turning when the nuts 2() are tightenedupon the Shanks ot' said bolts against the rear side of the beam.

ln the eyes ot' the eyebolts are litted longitudinally-curved shanks orstandards 19, carrying the earth-engaging shovels or blades 24;, whichlatter may be of any desired construction. lt will be readily seen thatthe blade-carrying shanks or standards are adjustable to a considerableextent and within a wide range by simply loosening and retightening thenuts upon the eyebolts. .By raising' or lowering the Shanks theinclination oi the blades with relation to the soil may be changed tothe extent that when the standards are lowered the earth-engagingimplements will merely skim the soil, while when the standards areraised the earth-engaging implements will dig into the soil and exercisea harrow action. Many intermediate positions are also possible. TheShanks may be turned axially, so as to present the points of the bladesstraight to the front or at any desired angle to the line of progress.By tightening the nuts upon the eyebolts it will be seen that thestandards will be clamped between the heads of said bolts and the upperand lower side members oi' the cultivator bar or head, there being threepoints oi' contact whereby great rigidity oi' attachment is insured, itbeing noted in connection therewith that the nuts may be tightened toany extent without twisting or turning the eyebolts, the heads oil whichenter between the side members oi the cultivator-head. The latter may beadjusted transversely or obliquely with relation to the annular ring ortrame, and the connection being made by means ot clips the ring or frameis not weakened by bolt-holes and may therefore be constructed oiAllight and inexpensive material, while at the same time the adjustment isnot limited to the distance between the bolt-holes, but may be effectedvery minutely.

In a device oi' the class described, a beam,

hook-bolts depending from said beam, a ring clamped adjustably upon thebeam by said bolts, a cultivator-head including upper and lower sidemembers spaced apart, clips connecting said head adjustably with thering,

eyebolts extending between the upper and lower side 'members of thecultivator-head the heads of said bolts being partly extended betweensaid side members to prevent turning or twistingl of said bolts,tightening-nuts upon the latter, and blade-carrying Shanks extendingthrough the eyes of the bolts, said shanks being longitudinally curvedand in engagement with the upper and lower side members of thecultivator-head and with the eyes of the bolts.

In testimony that I claim the foregoing as my own I have hereto afhxedmy signature in the presence of two witnesses.

ALONZO H. FENCE.
